losing wireless network while playing online game

I have a wireless network at home, actually one wired,
one wireless computer, that was working fine until my
sons both bought copies of Warcraft to play each other
over the internet. They were able to get on but the
wireless computer drops the connection soon after
starting play and then we can't access the wireless
network from that computer. We keep getting messages
saying there are multiple wireless networks available
when I click on our network name I keep getting the same
message over and can't connect.

Check that the router and the wireless card are set to
the same channel, and that you have changed the SSID from
the default value of MSHOME.

On the properties for the wireless network, add your
network to the preferred list, and make sure
that "connect to non-preferred networks" is unchecked.

Which router and wireless card are you using, and which
OSes?
